Which statement describes a magnetic azimuth?

Which statement describes a magnetic azimuth?

• A. Taken from a compass and measured from magnetic north
• B. Calculated from grid north with a ruler
• C. Measured from true north using a compass
• D. Derived from contour lines on the map

Answer: (C)

Magnetic azimuth is the angle from magnetic north to a target, measured clockwise. A compass uses magnetic north, so the reading you get with a compass is a magnetic azimuth. If you measure from true north, you’re dealing with a true azimuth, and you’d need to account for magnetic declination to relate it to magnetic north. Measuring from grid north or deriving from contour lines describes different references or map features, not magnetic north. In practice, you convert between true and magnetic azimuths by applying the local declination angle.
